Exterior design
Can you imagine a face without an expression?

Exterior design.
Every child recognises a 911, but can its
identit y be described in words? It can, by
looking more closely at the use of form,
proportions and contours. The roof line
tapers down into the rear. The wings are
higher than the front lid and, at the rear,
they add muscle. They give the 911 its
distinctive expression and leave you in
no doubt as to its temperament.
The overall appearance is low, wide and
sleek. Typically 911.
So, is every thing just the same as it has
been since 1963? Yes, and no. After all,
only those who change will remain true
to themselves – and we’ve changed. Our designers and engineers speak
guardedly about the 911 evolution.

Meanwhile, they continually manage to
take great strides forward with innova -
tions motivated by the principle that
these should be functional and perfectly
compatible. The result is a harmonious
overall concept that makes the new 911
a sportscar fit for the 21st century.
To show you what we mean, we should
start by looking at the car’s exterior. The
wheelbase of the new 911 is 100 mm
longer for improved driving stability and
cornering dynamics. Overhang is now
shorter at the front and rear, making the
new 911 look even more compact. The sporty overall impression is emphasised
by the lower roof line and a wider track at
the front – 46 mm on the 911 Carrera and
52 mm on the 911 Carrera S. For improved
aerodynamics, the exterior mirrors are now
mounted directly on the doors. Increased
agilit y is just one of the results of all these
refinements.
The silhouette is therefore typically 911
and t ypical in terms of its development,
which will now be described in more detail.

Engineering
Let’s forget the future for a moment.
As we discover it in the present.

Engineering.
What use is the engineering of tomorrow
when it can be found on the road today?
None. So let ’s turn to the here and now.
The engines, as you would expect,
are characterised by six horizontally
opposed cylinders. The 3.4-litre engine
in the 911 Carrera produces 257 kW
(350 hp); in the 911 Carrera S, the 3.8-
litre engine develops 294 kW (400 hp).
Both models are equipped with direct
fuel injection (DFI) and VarioCam Plus
for increased power and reduced fuel
consumption. This power is transmit ted
to the wheels by the new and efficient
7-speed manual gearbox or, optionally,
by Porsche Doppelkupplung (PDK), which offers gear changes with no interruption
in the flow of power.
Both engines deliver improved sport y
performance compared with the engine
in the previous model and yet fuel

consumption has been reduced by up
to 16 %. How was this achieved? One
explanation is the reduced capacit y of
3.4 litres in the 911 Carrera. Another is
the total redevelopment of the engine
peripherals with groundbreaking efficiency-
improving technologies.
As standard, these include the auto
start/stop function, electrical system
recuperation and intelligent thermal management as well as the new, energy-
saving electromechanical steering system
and, in the case of PDK, the introduction
of the coasting function (for more infor
-
mation, please refer to page 39 onwards).
The chassis is also packed with forward-
looking technology. Fit ted as standard
in the 911 Carrera S, Porsche Torque
Vectoring (PT V) increases dynamic perfor -
mance. Available as an option for the
S model, Porsche Dynamic Chassis Control
(PDCC) improves dynamic performance
further still. Dynamic engine mounts,
included as part of the optional Sport
Chrono Package, are now available for
the 911 Carrera models for the first time. These provide perceptibly more stable
handling under load change conditions
and in fast corners.
The new 911 has a light weight composite
construction in aluminium and steel. Used
extensively and in just the right places,
lightweight aluminium improves fuel
economy and dynamic performance and
helps to achieve a low weight to power
ratio of 4.7 kg / kW (3.5 kg / hp) for the
9 11 C a r r e r a S .
The future of the sportscar begins now.

It ’s easy, and even makes sense, to carry
on in your usual way, but what happens
if a sudden change of direction leaves
you thrown off course? Then, it all comes
down to personal strength.
A Porsche has a clear sense of purpose
and is the embodiment of strength.
It demonstrates this with sport y and pre -
cise handling and excellent road holding. With the optional Porsche Dynamic

Chassis Control (PDCC) for the S model
of the new 911, these characteristics can
be further accentuated: the 911 Carrera S
holds the road even bet ter and delivers
even sportier performance. PDCC is an active anti-roll system that
anticipates and reduces lateral body
movement during cornering manoeuvres.
In addition, it minimises the lateral insta
-
bilit y of the vehicle on uneven ground.
This effect is achieved with the aid of
hydraulic stabilising actuators in the form
of cylinders designed to optimise camber.
Lateral roll is counteracted by forces
generated at each individual wheel, based
on steering angle and lateral acceleration.

You appreciate directness.
But love a few twists and turns.

Porsche Dynamic Chassis Control (PDCC).The results are improved dynamic
performance and increased ride comfort
at all speeds, as well as optimised turn-in
and stable load transfer characteristics.
In simple terms, the vehicle holds the
road bet ter and you can steer through
corners faster and in a more relaxed
m a n n e r.
PDCC sets new standards for handling
performance, ride comfort and driving
pleasure. In the new 911, your ‘usual’
way suddenly becomes the Porsche way.

Included in the package are a performance
display, a digital and an analogue stop -
watch and the SPORT PLUS but ton. An
additional display in the steering wheel
and instrument cluster indicates whether
the SPORT but tons and Launch Control
have been activated.
On activation of SPORT PLUS mode,
Porsche Active Suspension Management
(PASM) and, in the S model, optional
Porsche Dynamic Chassis Control (PDCC)
switch to a harder damping set ting
and offer more direct steering and,
therefore, better road holding.
In SPORT PLUS mode, the trigger thresh -
old for PSM is raised. Agilit y is perceptibly
enhanced when braking for corners with
PSM, allowing sportier braking and exit
acceleration. For maximum dexterit y,
PSM can be set to standby while the car
is still in SPORT PLUS mode. For safet y,
it is set to intervene automatically only
when ABS assistance is required on both
the front wheels.
In combination with PDK, the Sport
Chrono Package has t wo additional functions for a sport y drive that borders
on a motorsport experience. The first

is ‘Launch Control’, which can be used
on the track to achieve the best possible
standing start – a racing start.
The second function is the ‘motorsport-
derived gearshif t strategy’. Using this,
Porsche Doppelkupplung (PDK) is geared
up for extremely short shift times and optimum shift points for the maximum
acceleration available. This combination
of uncompromising and involving perfor
-
mance is ideal for the racetrack.
A key component of the Sport Chrono
Package is the stopwatch mounted on
the dashboard. In conjunction with the
optional PCM, a special performance
display enables you to view store and evaluate lap times or other driving
times. It shows the total driving time,
lap distance, lap number and lap times
re c o rde d s o f a r.
A feature of the Sport Chrono Package
borrowed from motorsport is the dynamic
engine mounts. These exploit the laws

of physics for your own driving pleasure.
Dynamic engine mounts.
You don’t have to take the new 911 onto
the racetrack. But you can, more so
than ever, because dynamic engine
mounts are now included as part of the
Sport Chrono Package. Based on the
engine mounts of the 911 GT3 and
911 Turbo models, it is the first time that they have been available for the

911 Carrera. Even if track racing is
not for you, dynamic engine mounts
make a decisive contribution to dynamic
performance on the road, too.
The electronically controlled system mini -
mises the oscillations and vibrations of the
entire drive train, especially the engine.
The engine is bolted to the body by t wo
mounts. Like any mass, it obeys the law
of inertia. This means that it will continue
moving in a uniformly straight line unless
some force causes it to change direction.
Put more simply: when you are driving
into a bend, the vehicle will follow your
steering but, at first, the mass of the
engine will not. This means that the rear
of the vehicle will ultimately be pushed
out wards as a result of the engine’s
force of inertia.
Dynamic engine mounts minimise
this effect. Steering angle and both
longitudinal and lateral acceleration
are constantly recorded by sensors. The stiffness and damping performance
of the engine mounts adapt to changes
in driving st yle and road surface condi
-
tions, which is achieved by use of a fluid
magnetised in an electrically generated
field. This results in greater traction
and perceptibly more stable handling
under load change conditions and in
fast corners.

In the 911, there is a point at which all
forces come together. The steering wheel
is the most important inter face bet ween
the driver and the sportscar. This is

why all available steering wheels feature
a high-grip steering wheel rim in smooth-
finish leather and offer outstanding
ergonomics. A full -size airbag is integrated
as st a n d a rd .SportDesign steering wheel.
As with the sports steering wheel, the
optional SportDesign steering wheel
is adjustable for both height and reach
and, thanks to its grip mouldings, it’s
in safe hands – even on the sportiest
of drives.
Sports steering wheel.
The sports steering wheel is fit ted as
standard and adjusts up to 40 mm for
height and up to 60 mm for reach.
The optional multifunction steering
wheel has four function but tons and t wo thumbwheels for convenient operation

of audio, telephone and navigation
functions, TFT display and on-board
computer. On request, the steering
wheel is available in smooth-finish leather,
Aluminium Look, carbon or macassar. In conjunction with PDK, the steering
wheels are equipped with t wo ergonomic
gearshift switches enabling you to
change gear directly from the steering
wheel. With the optional Sport Chrono
Package, the steering wheel also features
a display above the airbag module to
inform you whether the SPORT, SPORT
PLUS and Launch Control functions have
been activated.
SportDesign steering wheel
In conjunction with PDK, the steering
wheel features t wo gearshif t paddles.
These are made from a strong alloy and
are ergonomically located behind the
lef t- and right- hand steering wheel
spokes. Pull the right-hand paddle and
PDK shifts up. Pull the left-hand paddle and PDK shifts down. When PDK has
been combined with the optional Sport
Chrono Package, the left- and right-hand
spokes additionally feature a display

that tells you whether the SPORT, SPORT
PLUS and Launch Control functions have
been activated. Steering wheel heating.
For increased comfort on cold days,
steering wheel heating is available as
an option for the sports steering wheel
and multifunction steering wheels
(only in conjunction with seat heating).
The heating is operated by a but ton
on the rear of the lower steering wheel
spoke.
